Go over to the Integra forum... Not many Accords have a B18C engine.

Search for "LS-VTEC" because that's what this conversion is usually called.

You'll need at least this stuff:
VTEC solenoid with it's oil pressure switch
Intake manifold with IAB, along with the vacuum canister, solenoid, etc.
A B18C1 engine wiring harness.
An ECU from a GSR to make it all work.

The reason you want the intake manifold is the IAB butterflys are what makes that "SOUND of a VTEC". It's not actually the vtec.
